The Dark Rebirth: A FNAF Security Breach AU by violetroses1997

After the events of Help Wanted, William (as Glitchtrap) decides to clone himself and transfer his soul into this new body since cloning is a form of technology available in the distant future. Using Remnant and mad science, a clone of himself is created successfully (with some assistance from Vanny). However something goes wrong as the clone stops rapidly growing when it reaches its child stage and suddenly awakens, breaking the vat it was kept in during the process. Worse, it seems the clone has run away, refusing to be William's Vessel. Cue the start of Security Breach where the clone hides within a sleeping Glamrock Freddy to avoid being caught by Vanny. When Glamrock Freddy wakes up later and asks his name, the clone decides to rename himself as "Gregory". Meanwhile, Vanny fails to locate the clone and so, Glitchtrap asks Vanny if she can get him into the Pizzaplex system so that he can assist her in finding and capturing him. She agrees, lets him into system and he corrupts the animatronics to obey him in the process... The Art of Gregory and William is an Art Commission done by @fiorellapiedo on Instagram.

Some Time To Kill (UndertalexCreepypasta) by shxbwesx

Sans' life on the surface has been going well enough, but how long will it last. Will Frisk take it all away with another reset? Too much paranoia can attract attention... (This is an Undertale and creepypasta crossover I hope you enjoy :P) (Inspired by BubblyShip (marry me))

Flower crown fit for a king by scarystickers

It's been a couple months since the events of what happened at the Mega Pizzaplex. Gregory freed Vanessa and she adopted him. Vanessa kept her job due to how much money she was making and how useful having that money was when taking care of a child. Vanessa is trying her best to take care of Gregory while still being traumatized herself. It's a process but hopefully she'll be able to heal, right? During the last month of school for Gregory he learned how to make flower crowns! This spirals to Gregory becoming fascinated by plants, specifically flowers as a whole and plans to give the animatronics a bit of nature since they aren't allowed outside the Pizzaplex. Or Gregory learns how to make flower crowns, goes to the Pizzaplex and is a chaotic child who gets bored easily and does research on flowers. He's determined to show the animatronics part of the world that they don't get to see. Meanwhile Vanessa still isn't over what happened while she was Vanny. Hopefully they'll get to heal from what happened and don't allow some sad angst to get in the way. - Copy and pasted from ao3 so format might be weird or it might have words in places it shouldn't or whatever

A new place with new friends by TheDragonOfBalance

It was a nice day in the underground today, until something...unexpected happened. Who are these new humans? How did they fall down in the underground? But most importantly are they a threat? Are they nothing but a bunch of dirty killers?...Or are they friends? This is my first story, quick warning but I do hope you still enjoy this as much as I enjoyed writing this. Also all characters belong to their respective owners and creators except for the two new humans

The First Human [X Sans] {COMPLETE} by RaeTheStar

Imagine Undertale, but Chara never showed up. Chara wasn't the first human in the Underground. What if a glitch occurred, and you fell down instead? You fell into the Underground, but you cant remember your previous life. Now, you are surrounded by strange monsters, who have also never seen a human before. Will they let you live? [written 2017]

Don't Forget [Sans x Female Reader] by GabrielXander

You would think that with how shit your luck is, you would've been dead day one since falling into the Underground filled with scary monsters and a few spooky skeletons. However, much to your surprise, that did not happen (yet). You know how you ended up here, but you don't know... HOW. You're actually in the GAME Undertale now. And to make matters worse, there are some people who KNOW. You're surviving the best you can, but things are only going to get weirder from here on out. Gaster apparently needs your help? You're using the DJ to go to different AU's? You are gay now?- Okay, maybe that last one is just a joke, but still! You can only hope that your instincts are enough to keep you alive in these trenches. On God, they tryin' to drown you in this hoe! {Available on Patreon, Quotev, and Ao3 under GabrielXander}

Timelines (A Doctor Who/Undertale crossover) by introverted-actress

What happens when a human gets tired of resets? When the thrill of a genocide route becomes boring and mundane? This is exactly what happens to Frisk. They spent so much time going through reset after reset that now they are growing tired of it. However, little do they know that their next timeline will be one of the most interesting they've ever had. When Frisk resets after an incomplete genocide, it captures the attention of a certain alien Timelord called The Doctor. He has to travel between dimensions to investigate this strange anomaly, but ends up with an adventure much more strange than he had initially anticipated. This timeline is breaking. The entire reality is being torn apart and it's up to Frisk, Sans, and The Doctor to stop it. (Disclaimer: I do not own Doctor Who or Undertale. The only thing I own is the plot line and the writing.) Cover art by @GodOfChaos3900

Reckoning Tale-An Undertale Fanfiction Novel by Serena_Walken

(Complete)Eighteen years ago, Frisk left the Underground, but there was another barrier to face before the monsters were freed. When Frisk comes back as an adult though, she must pass tests that 'destroy her human soul' in order to save the monsters, and Toriel won't allow it. Banished and unable to return, Frisk is stuck back on the surface. Knowing that freedom can only be won with 'humanity', Sans goes to the surface to trade Frisk some of his 'monster' for her 'humanity', so he can help too. However, neither of them know where these tests will lead . . . or how far the truth really goes. A barrier is more than a gateway . . .
